That's right, we have actually released plans that we created! The plans will enable you to build and even tune a small desktop-sized Hinged Counterweight Trebuchet (HCW) that will throw a small rubber ball 20 feet! Begin war today on your cubicle neighbors! See the page here: Mini-HCW Plans.

In other news, if you are in the Rochester, NY area this Saturday (May 7, 2011), be sure to come by Imagine RIT. It is free, and is a great time for parents and children alike. We will be demonstrating Melon Felon, Janus, and a FAT Whipper nicknamed GRAW. We will also be showing some of the engineering work we undergo in designing these machines along with some videos of our machines and also some stuff from the World Championships of Punkin Chunkin.

Use "common sense" when operating trebuchets and catapults. Even little ones can be dangerous. Do not place anything you are not willing to lose in the plane of the arm rotation (this includes yourself, body parts, car windshields, cameras, etc). These catapults and trebuchets are capable of throwing just as far backwards as forwards, and the use of a backstop of some sort is recommended, though the use of one does not make the region behind it safe.

Also, just because the throw got away safely downrange does not mean the end of the danger. The arm is likely still swinging wildly along with the counterweight, and there is a sling whipping around. One thing many people fail to take into account is this sling; some people put a metal ring on the slip end of the sling and this ring can HURT when whipping around!

Have fun hurling, but please KEEP IT SAFE!!!
